Twenty four hours after a Metro-North train accident in New York City there were still many unanswered questions. The
derailment was the first fatal crash in the commuter railroad’s 30 year
history. Four passengers died and more than 60 others were injured.

"Nobody really knows
what happened so far in terms of why the accident occurred but, what is clear is
that there are four people who lost their lives,” said New York Mayor Michael
Bloomberg. “It's very tragic."

As bad as this derailment was, officials say it could have been a lot worse if it had happened on a week day. The Sunday morning train was only about half full.

The cars were still
scattered along the shut-down rail line and thousands of commuters were
scrambling to find a different route to the city on Monday.
